The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Experiment**: Rutherford conducted an experiment where he fired alpha particles at a thin gold foil. This was a groundbreaking experiment in understanding atomic structure. 2. **Observation of Alpha Particles**: Most of the alpha particles passed straight through the foil, while a small fraction were deflected at large angles, and some even bounced back. 3. **Interpretation of Results**: Rutherford interpreted these results to mean that the atom is mostly empty space, with a very small, dense, positively charged center that repelled the positively charged alpha particles. 4. **Conclusion of the Discovery**: From this experiment, Rutherford concluded that the atom has a nucleus, which contains most of the atom's mass and is positively charged. 5. **Naming the Discovery**: He named this central part of the atom the "nucleus." Thus, Rutherford's alpha particle scattering experiment resulted in the discovery of the nucleus. ---
